■要約(英語) Downsizing of distribution lines while maintaining feasibility of network reconfigurations would save monetary costs in a distribution system planning. In this study, we propose a method to find distribution lines with reducible capacities based on a set of non-dominated solutions for network reconfiguration problem under the condition that appropriate reconfigurations can be performed even after the downsizing. To alleviate the computational burden, the proposed method consists of three steps. First, (i) the current flowing on distribution lines when performing the network reconfigurations are found by a developed evolutionary algorithm for solving many-objective network reconfiguration problems. Second, (ii) the distribution system operator specifies his or her preferred solutions among them to perform reliable network reconfiguration for all maintenance areas. The maximum current flowing on lines are computed based on the specified preferred solutions. Finally, (iii) distribution lines with possibilities of the downsizing are chosen based on the maximum current flowing on the lines before/during/after the reconfiguration and then feasibility of reconfigurations after the downsizing are validated. The computational experiment using a large-scale distribution system model demonstrates that the proposed method identifies the distribution lines with reducible capacities and their line types after the possible downsizing.
